Main Bearing Set Coated Nissan 2.0L SR20DE/DET

The Main Bearing Set Coated Nissan 2.0L SR20DE/DET from ACL Bearings is a precision-engineered bottom-end component built for builders and enthusiasts demanding reliability in high-performance applications. Whether you're assembling a stock rebuild or preparing for forced induction, this bearing set delivers the durability and precision fit required for sustained engine operation. Designed specifically for the SR20 platform—one of the most popular platforms for tuning and modification—this coated bearing kit addresses the real-world demands of both street and competition builds.

This main bearing set features ACL's proven race-series construction with an extra oil clearance specification, a critical factor for engines operating under boost or sustained high RPM. The coating applied to the bearing surface improves load distribution, reduces friction, and extends bearing life under stress—essential when engine output climbs beyond stock parameters. The standard size configuration makes this kit suitable for original bore dimensions, eliminating the need for crankshaft undersize machining while maintaining proper journal clearances. The compact footprint (3 x 2.25 x 4 inches) and lightweight construction (0.6 lbs) ensure efficient packaging within the SR20 block without compromising bearing wall thickness or durability.

This bearing set is ideal for S13/S14 owners, 240SX platform builders, and anyone running a SR20DE or turbocharged SR20DET engine in street, drift, or circuit applications. Installation requires proper torque specifications and oil clearance verification during assembly—standard practice for any quality bottom-end rebuild. Pairing this bearing kit with quality fasteners, proper oiling strategy, and correct assembly procedures ensures the foundation for reliable power delivery. Mechanics and engine builders trust ACL's heritage in racing applications, making this set a proven choice for both restoration and modification projects targeting longevity and performance.
